The author verified, in experiments with seventy heads of cattle, the presence of Eurythrema coelomaticum, using a subcutaneous test in which injections were applied with a syringe “Carpule”, in the wrinkles of the skin under the tail head. Antigen produced by the trematodes, obtained in “Cocca” liquid was used. The diagnosis was made by examining the pancreas after the slaughter of the animals. The positive reactions did not have any relation to the amount of infestation. The negative cases were rare; of the seventy animals examined, only four did not shew any response to the treatment, even though they were infested with the parasites. Only one case showed positive response, notwithstanding the fact that it was not infested.
